Thread: Any relation to running lean triggering a cel?

When cruising i in my b14 ive noticed my narrowband AFR (i know i know, wideband comming soon) will drop to the lean side and trigger the cel. it does this constantly on and off, on and off. ive tried to pull codes and nothing is stored. I know i really need to get it to a shop to get tune cleaned up a bit also.

Setup as follows
DET with VE head
t25
370's @4bar
timing @ 15 deg
B13 realtime with stepdown harness
Apexi AVCR and VAFC

come back when you get a wideband it will make it easier to help you out

yea thats what im thinking and i should have one on the way by fri...
